The game plays as a [[2D computer graphics|2D]] [[sidescrolling]] [[platform game|platformer]] with elements of a [[run and gun (video game)|run and gun]] game as well. The player controls Jim and must maneuver him through the level while avoiding obstacles and enemies. The player can use Jim's gun as a method of shooting enemies, or his worm body as a whip for whipping enemies. The whip move also allows the player to grab hold of, and swing from, certain hooks. Some levels have additional requirements beyond merely getting to the end of the level. For example, the level "For Pete's Sake", involves making sure the computer-controlled Peter Puppy character gets through the level unharmed, which is accomplished by whipping him to make him jump over pits, and defeating enemies before they can damage him. Failure to do so results in Peter lashing out at Jim, depleting his health.

Levels commonly culminate with a [[Boss (video gaming)|boss battle]]. The game incorporates a large variety of villains in the boss battles, including Hickboy, Psy-Crow, Queen Slug-for-a-Butt, Evil the Cat, Bob the Killer Goldfish, Major Mucus, and Professor Monkey-for-a-Head-exclusive Robotic Chicken. Two villains made their only appearance in this game: Chuck, a junkyard man with a tendency to vomit bizarre objects; and Doc [[Duodenum]], a crazed organ of a giant alien.

In between most levels, a racing level called "Andy Asteroids" is played. Unlike the rest of the game, it places the viewpoint behind Jim. The player must direct Jim on his rocket, in a race against Psy-Crow, through a tube-like structure while collecting items and boosts and avoiding asteroids. If the player wins, the next level is started instantly. If Psy-Crow wins, a boss fight against him must be won to progress to the next level.

Other variations in gameplay occur throughout the game as well, such as a competitive bungee-jumping and fighting level, and an underwater maze that must be traversed both within a time limit and without crashing too many times.<ref name="wii.ign.com">{{cite web|url=http://wii.ign.com/articles/924/924151p1.html|title=Earthworm Jim Review|work=IGN|access-date=4 October 2014|archive-url=https://web.archive.org/web/20120323084613/http://wii.ign.com/articles/924/924151p1.html|archive-date=2012-03-23|url-status=dead}}</ref>
